the Thing from Venus
At a dinner party with their wives, NASA scientist Dr. Keith Ritchie (Anthony Huston) reveals to his colleague Dr. Curt Taylor (John Agar) that he has secretly been in communication with an alien from Venus named Zontar who he claims is coming to Earth to solve all of the world's problems. However, as soon as Zontar arrives on Earth via a fallen laser satellite it quickly becomes obvious that the three-eyed, bat-winged, skeletal black creature has a hidden agenda, as it begins causing local power outages that stop telephones, automobiles and even running water from working, and it starts taking control of people's minds using flying lobster-like "injecto-pods" that sprout from its wings. Only after his wife is killed does Ritchie finally realize that Zontar has come not as a savior but as a conqueror, and he goes to confront the hideous alien in the sulfur spring-heated cave that it has made its secret base.
